Exo-Stellar Civilizations (Narration Only) 14.03.2021

Our future in the galaxy is typically envisioned as tied to the stars, be it on planets orbiting them or vast megastructures fueled by the alien suns, and yet the true future of humanity might be to dwell in the vast gulfs between the stars or even in a galaxy in which those stars have ceased to exist.

Killing Stars (Narration Only) 11.03.2021

When the largest of stars dies, the supernova they produce can outshine a whole galaxy, and potentially sterilize vast swathes of space. Future civilizations will need to be able to prevent or mitigate such events, though some might seek to artificially ignite a nova.
